研究了以含环状非共轭双烯配体的1,5-环辛二烯三羰基铁为原料,与芳基锂反应,用Et3OBF4烷基化,以进一步研究不同环烯烃配体在卡宾配合物中的异构化行为和对反应产物的影响,用元素分析,红外光谱,核磁共振氢谱,质谱确定了八个新化合物的结构.用X-射线结构测定进一步证实了9-(η^6-芳烃二羰基铁)-9-三甲基硅氧基双环[4.2.1]壬-2-烯的分子结构.

Novel h6-arene(dicarbonyl) iron complexes I (R = H, 3-, 4-Me, 4-Ph; R1 = Me3Si, Et) have been prepared by the reaction of 1,5-cyclooctadiene(tricarbonyl)iron with RC6H4Li and subsequent reaction of the acylmetallates with Me3SiCl or Et3OBF4, resp. Oxidation of I (R = H, 4-Me; R1 = Me3Si) with (NH4)2Ce(NO3)6 in ethanol solution at -30癈 led to the dissociation of arene ligands to give 9-aryl-9-trimethylsiloxybicyclo[4.2.1]non-2-enes II in high yields. I and II were characterized by elemental analyses, IR, 1H NMR and mass spectra. The structure of II (R = H, R1 = Me3Si) is further confirmed by x-ray diffraction anal.
